Procedure

A solution of 1-oxalomethyl-1H-tetrazole-5-thiol (10.0 g) and hydroxylamine hydrochloride (4.8 g) in water (100 ml) was adjusted to pH 6.0 with 2N aqueous solution of sodium hydroxide and stirred at room temperature for 3.5 hours. The solution was acidified with 10% hydrochloric acid to pH 2.0, extracted with a mixture of tetrahydrofuran and ethyl acetate (1:1). The extract was washed with a saturated aqueous solution of sodium chloride, dried over magnesium sulfate and evaporated to give 1-(2-carboxy-2-hydroxyiminoethyl)-1H-tetrazole-5-thiol (5.61 g).
